William F. Fu qua, Canton, Ohio Application September 14, 1944, Serial No. 554,078

My invention relates in general to sealing strips 4' and structures with sealing strips, and more particularly my invention relates to combinations including frames forming and extending about openings, such as door frames, window frames,

storm sash frames, chest or'box topframes, and the like, closures fitting in or across the frame openings, the closures being such as doors, windows, storm sashes, chest ,or box tops, and sealing strips on the-frames on, closures for 'sealing'the closures in or across the frames when the closures are in the closed position.

Also my invention relates to siding, paneling, and other building or structural combinations,

where it is desirable to provide sealing stripsbetween individual pieces or elements.

My present invention constitutes improvements in the Sealing strips and structures with sealing strips, set forth in my prior application for United States Letters Patent, filed June 12, 1944, Serial No. 539,957.

In my said prior application, I disclose broadly in one of two overlapping pieces or elements, a longitudinally extending groove in which is self-engagingly fitted a longitudinally extending sealing strip preferably formed of bronze or similar resilient metal, the sealing strip having an unsymmetrical U transverse cross section and including laterally space leg walls, one leg wall being narrower than the other and being located entirely in the groove, and the other broader leg wall extending in sealing and overlapping abutment with the other piece or element.

The objects of the present invention include the provision'of an improved form of sealing strip having an unsymmetrical U transverse cross section, as compared with the form of such sealing strip set forth in my said prior application, Serial No. 539,957, whereby the improved sealing strip may be produced and used with somewhat greater economy and facility thanthe sealing strip .of my said prior application.

Further objects of the present invention includethe provision of improved combinations including overlapping structural or building pieces or elements and the improved sealing strips for sealing the overlapping pieces or elements.

The foregoing and other objects are attained by the sealing strips, structures, pieces, elements, members, units,- parts,-combinations; and subcombinations, which comprise the present invention, the nature of which is set forth in the following general statement, and preferred embodiments of which together with their mode of use are set forth by way of example in the following description, and which are particularly and distinctly pointed out and set-forth in the appended claims forming part hereof.

The nature of the present invention may be stated in general .terms as-including a sealing 3 Claims. (CI. 20-69) 2 strip having lopsided or unsymmetrical U cross section, and whichconstitutes an improvement of such a sealing strip as set forth broadly and in detail in my said prior application, Serial No.

The present improved sealing stripis preferably formed of springmetal, and hasanunsymmetrical U cross section, and includes a bottom wall and a narrower leg wall and a broader wall extending from the-opposite preferably parallel sides of the bottom wall The leg walls are. thus laterally spaced from each other, and the broader leg wall preferably includes reversely angled bands having sides parallel with each other and the sides of the bottom wall, andthenarrower leg wall is transversely curved and its outer side is preferably sharp cornered forimproved selfengagement in the retaining groove of the piece, element or-member. in which it ismounted.

Thepresent improvements also include improved combinations of the improved sealing strips with" overlapping structural or building members, pieces, or elements, which are desired to be sealed, and which have a wide variety of specific forms and uses.

By way of example preferred embodiments of the improved sealing strip and improved combinations and subcombi-nations including the same, are illustrated in the accompanying drawings forming part hereof, in which Figure l is an enlarged oblique view of one of the improved sealing strips in its unrestrained condition as formed; and before being-placed in self-engaging position in the groove of the strip holder member of overlapping 01w overlappable members; I

Similar numerals refer to similar parts throughout the drawings.

The improved sealing strip-indicated generally by i is made of spring metal, preferably bronze, and has a transverse cross section Which-is generally that of a lopsided or unsymmetrical U, and includes a preferably parallel sided bottom wall [5, from the sides OI substantially rightangled corners l1 and I8 of' extend, respectively, preferably, parallel sided leg walls indicated gerimany by 19' and 20. I p

The 'outer side 2 of the'leg wall i9 is preferably enlarged, which as shown, is effected by forming the sealing strip l5 from sheet metal and providing a back-folded band 22 at the leg wall outer side 2|.

For the purposes of the present improvements, the outer side 23 of the leg wall 20 is sharp cornered which is effected by shearing or" grinding the side 23.

The width of the leg wall l9 between its sides IT and 2| is substantially greater than the width of the leg wall 20 between its sides l8 and 23. In other words the leg wall 20 is narrower than the broader leg wall l-9.

In the leg wall l9; a central longitudinal flat bandl 9 -l is reversely angled with respect to the adjacent side by side flat bands l9'-2 and l9"3.

For the purposes of the present im rovements, the leg wall 23 is transversely curved; and the curvature is outwardly concave in the outer face 24 between the leg wall sides I8 and 23', and in- Wardly convex in the inner face 25- opposite the broader leg wall l9.

As shown in Figure I, in unrestrained condition, as made, and before insertion into a holder member, in eachlopsided U- sea-ling strip l5, the wider or broader leg wall [9 has a substantial inclination towards the shorter or narrower leg wall 20' away from the plane perpendicular to the bottom wall l5 through the corner l1. Also, for the purposes of the present improvements, the outer side 23 of the narrower leg wall Z'Ois offset outwardly a substantial distance from its side" or corner I8 commen with the bottom wall, and the bottom wall is substantially radial with respect to the transvers'ely curved narrower leg wall 20;

As shown, the bottom wall I6 is flat, but it may have any other desired form, such as a transverse overall curvature, corrugation, or the like.

In Fig. 2, oneof the improved sealing strips I5 is shown in combination with overlapping members 26 and 21, the overlapping member 26 being a rabbet strip holder member, and having a rectangular sealing strip holder groove 28 formed in one rabbet face 29 thereof, which face 29" is at 4 right angles to the other rabbet face 38. The rabbet face 39 constitutes an extension of one side face 3| of the rectangular groove 28, which has" an opposite side face 32 and a bottom face 33.

The rabbet face 35 is also the inside face of a flange 34 overlapping an opposite parallel face 35 of the member 21 which has another face 36 at right angles to the face 35 and parallel with the rabbet face 29 of the member 26. The face 36 of the member 2'! also extends across the outer opening of the rectangular groove 28.

The construction and arrangement of these overlapping members 25 and 27 are substantially the same as the similar members shown in Fig. 4 of my said prior application, Serial No. 539,957.

One of the improved sealing strips i5 is inserted in the rectangular groove 28 with the bottom wall l6 of the strip abutting the groove bottom face 33, and with the strip broader leg wall l5 extending out of the groove alongside the rabbet face 30 of the flange 34 and between the face 30 and the oppositefac 35 of the overlapped member 2-7. The narrower leg wall 25 of the sealing strip 15 the groove 28 is in self-engaging restrained position, with the outer sharp corner 23| of its outer side 23 abutting against th groove face 32.

If the material of the sealing strip holding member 26 is wood or other material softer than the spring metal from which the sealing strip I5 is preferably made, then the sharp outer corner 23-l of the outer side '23 of the narrower leg wall 20 will gouge into the adjacent groove face 32.

In Fig. 3 is shown a combination including improved overlapping sheet metal members 26'l and EF -l which are externally generally similar to the members 28 and 2?, but in the sheet metal members 26l the groove 23-! is provided with a flange 3'i--l extending across the outer end of the groove face 32-1, providing an abutment for the outer corner 23 of the improved sealing strip l5 located in the groove 2ill.

In Fig. 4, another form of improved overlapping sheet metal members 252 and 2"l2 are shown in which both members are externally rabbetted. In the member 2'32, the groove 2s-2 in which is located a sealing strip I5, has a side face 322 sloping from the groove bottom face 33--2 towards the groove side face 3l-2. The sloping groove side face 322 thus constitutes a sloping detent for the curved sealing strip leg wall at 20.

In Fig; 5, the overlapping members 263 and 25'@ are formed of cast or molded material, and the groove 28-4 is provided with a retaining flange 37-4 similar in function to the retaining flange 3 'll. A sealing strip 25 is located in the groove 28-4.

In Fig. 6 is shown a panel'wall construction indicated generally by 38 and including a stud 39 against one face of which are abutted spaced side bands 40 of panels 4|.

Between the spaced side faces of the panels 4| is located a T batten 42 including inner rabbets having laterally opening grooves 285 formed therein in each of which is located a sealing strip l5 in sealing abutment with one of the panel side bands 49.

In Fig. 7 is shown an improved construction for a chest top and the like including the improved sealing strips, and which includes walls forming a chest 45 having an upwardly opening rectangular upper end indicated generally by 46 and which may be said to constitute a rectangular frame.

A cover top wall 41 extends across the upper faces of the rectangular frame 36, and the top wall 41 is provided on its under side with rectangular rabbets as shown, which overlap the members of the frame M5, and the rectangular rabbets of the top wall 41 are provided with horizontally opening or downwardly opening strip holder grooves 28-45 in each of which is located an improved sealing strip I5. The top wall 41 is connected by hinges 48 at one side with one of the members of the frame 46.

In Fig. 8 is shown a ship lap wall construction including the improved sealing strips, and which is indicated generally by 59 and includes studs 5|, one of which is shown, upon which are nailed in the usual manner undersiding 52, and horizontally extending ship lap pieces or members 53 are nailed upon the siding 52.

Each ship lap piece or member 53 is modifled from the usual form of ship lap and includes at its wider side a rabbet outer band 26-? which overlaps the outer band 21-? of the adjacent member. Each rabbeted wider ship lap band 26-! is provided with a strip holder groove 28-? therein, in which is located one of the improved sealing strips I5.

In Figs. 9 to 13, inclusive, is shown an improved outwardly swinging casement window construction including the improved sealing strips, and in which the several sectional views Figs. 10 to 13, inclusive, each show an arrange-- ment of overlapping members including a rabbeted member having a downwardly opening, or a horizontal opening, or a laterally opening holder groove 28-8 formed therein, in each of which is self-engaged one of the improved sealing strips [5.

In Fig. 14 is shown a combination of overlapping members for a separable frame for a built-in window frame and closures for the separable frame, and including the improved sealing strips hereof, the figure showing lower separable frame and closure members, and being generally similar to Fig. 10 by my prior appication, Serial No. 539,957, but including a horizontally opening strip holder groove 28-9 with one of the improved sealing strips l5 therein, instead of the upwardly opening groove shown in my said prior application.

Thus, it will be seen that each of the above described combinations includes one or more sets of overlapping members, one of which is a rabbeted member having a strip holder groove formed therein and having one of the improved sealing strips self-engaging therein. The manifold adaptability of the fundamental combination of the overlapping members, one of which is a rabbeted member having a holder groove formed therein and one of the improved sealing strip self-engaging therein is thus clearly set forth.

The embodiments of the present invention illustrated and described herein are by way of example, and the scope of the present invention is not limited to the same or to the particular details thereof, but is commensurate with any and all novel subject matter contained herein which may at any time properly under the United States patent laws be set forth in the claims hereof or originating herein, and the elements of any of such claims are intended to include their functional or structural equivalents.
